Introduction
Diagnose lung cancer through clinical manifestations, chest CT, and percutaneous lung biopsy. Lung cancer causes symptoms such as irritating dry cough, hemoptysis, dull or mild chest pain, chest tightness, and even systemic failure. Chest CT clearly identifies the location, size, and morphological characteristics of the lesion, allowing for an initial assessment of whether lung cancer is present. Percutaneous lung biopsy obtains tissue samples from within the tumor for pathological examination to confirm the diagnosis.
Lung cancer can be diagnosed through clinical manifestations, chest CT, percutaneous lung biopsy, and other methods. The details are as follows:
1. Clinical Manifestations
In the early stages, lung cancer typically does not present obvious symptoms. As the disease progresses, it may cause symptoms such as irritative dry cough, hemoptysis (coughing up blood), dull or dull-aching chest pain, chest tightness, and even systemic failure.
2. Chest CT
Chest CT imaging can clearly identify the location, size, and morphological characteristics of lesions, allowing for an initial assessment of whether lung cancer is present. It is an effective screening tool for lung cancer.
3. Percutaneous Lung Biopsy
Percutaneous lung biopsy involves extracting tissue samples from within the suspicious mass for pathological examination, which helps confirm the presence of lung cancer and determine whether the lesion is benign or malignant.
In addition, diseases can also be diagnosed via bronchoscopy. After a diagnosis of lung cancer is confirmed, active treatment under medical supervision is necessary to reduce the impact of the disease on the body.
